idena-js

Installing the library
The following instructions assume you have a project already created, and you have npm installed and operable.
$ npm install idena-js
Import the library in your project
import { Idena, LocalKeyStore } from "idena-js";
Configuration
import { Idena, LocalKeyStore } from "idena-js";
​
const provider = new LocalKeyStore();
const idena = new Idena(provider);
Example
Create random address and import
This will import your private key in memory letting idena object to sign transaction using such key.
const provider = new LocalKeyStore();
const idena = new Idena(provider);
Import private key
This will import your private key in memory letting idena object to sign transaction using such key.
const privateKey = "6a666fb86f57ca37c333768982047781a4a2c31a902a89ee8c2b5bc7e12da444";
const provider = new LocalKeyStore(privateKey);
const idena = new Idena(provider);
Transfer
The transfer operation requires an idena object with an imported key having some funds.
const to = "0xab5801a7d398351b8be11c439e05c5b3259aec9b";
const amount = 0.001;
const operation = await idena.transfer({ amount, to });
console.log(`Hash: ${operation.hash}`);
Wait for transaction mining
When a transaction is injected an Operation object is returned. You can use the confirmation method to wait for an operation confirmation.
const to = "0xab5801a7d398351b8be11c439e05c5b3259aec9b";
const amount = 0.001;
const operation = await idena.transfer({ amount, to });
await operation.confirmation();
console.log(`Hash: ${operation.hash}`);
Bulk transactions 
You can also send more transactions in bulk.
let operations = await idena.bulkTransactions([
    { amount: 6.12, to: "0xab5801a7d398351b8be11c439e05c5b3259aec9b" },
    { amount: 2.12, to: "0xf8db1ee1be12b28aa12477fc66b296dccfa66609" },
    { amount: 4.93, to: "0xbe314949e2b9d14c27fa6785323f7cfc9250f92a" }
]);
operations = await Promise.all(operations.map(op => op.confirmation()));
operations.forEach(op => console.log(`Hash: ${op.hash}`));
Balance
Following example shows how to retrieve balance and stake (where stake are the balance plus the frozen DNA due staking/mining activity).
const address = "0xcf979f9472e38d45c577394747a3028ea7433bb5";
const { balance, stake } = await idena.getBalanceByAddress(address);
console.log(balance, stake);
Identity
This method returns an Identity object about identity address. 
const address = "0xcf979f9472e38d45c577394747a3028ea7433bb5";
const identity = await idena.getIdentityByAddress(address);
console.log(identity);
Retrieve address
const address = await idena.getProvider().getAddress();
Retrieve current epoch
const epoch = await idena.getProvider().getEpoch();
